SPECIFICATION forming part of Letters Patent No. 718,748, dated January20, 1903.

Application filed March 10, 1902. Serial No. 97,523. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK J. BOEHM, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented new and usefulImprovements in a Combined Tweezers and Magnifying-Glass, of which thefollowing is a full, clear, and exact description.

My invention relates to combined tweezers and magnifying-glasses; andthe object that I have in view is the provision of a compact implementor tool which may easily be carried in the pocket or otherwise on thepersonby a Workman, mechanic, or by others, said implement having itsparts so combined that in its folded condition the lens or glass will behoused and protected by the members or leaves forming the tweezers.

The implement can be used for a variety of purposes which will readilysuggest themselves to the mind; but I may mention that it is especiallyuseful to workmen in locating and extracting splinters from the hand, inexamining pieces of work or specimens when enlarged by the lens, &c.

In my article the lens is detachably and foldably connected to an armwhich is pivoted for adjustment relative to the tweezers; but suchdetachable and foldable features of the lens may be separately obtainedby means. constituting the equivalents for the specific embodiment ofthe invention to be hereinafter set forth.

With these ends in View the invention consists of an implement embodyingcertain novel features of construction, arrangement, and adaptation inthe several parts thereof, as will be hereinafter more fully described,and particularly defined by the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indi catecorresponding parts in all the figures.

Figure 1 is a plan View illustrating one mode of using the improvedinstrument. Fig. 2 is a perspective view illustrating the several partsdetached one from the other. Fig. 3 is a plan view of the implement inits folded condition. Fig. 4 is an edge elevation of the instrumentshown by Fig. 3, and Fig. 5 is a more clearly by Figs. 2 and 5.

cross-section through the lens and its holder in the plane of the dottedline of 5 5ofFig. 3.

The tweezers consist of the members 5 6, which are united at their inneror rear ends by means of a rivet 7or its equivalent. The members of thetweezers are pointed or tapered toward their operative ends, as shown byFigs. 2 and 3, and, as is usual in devices of this character, themembers are made of elastic material, so that they will spring apart andnormally assume the positions indicated by Fig. 4.

8 designates an adjustable lens-carrying arm, the same consisting of athin flat piece of metal arranged to be interposed between the membersof the tweezers and having its inner end pivoted, as at 9, to thetweezers. I prefer to make this arm 8 shorter than the tweezers, and thefree end portion of the arm is provided with a socket 10, the same beingpreferably of the tubular form shown by Fig. 2 and indicated in Figs. 1and 4:. This socket is adapted to detachably and adjustably receive thelens-holder l1, and this lens-holder is carried by the arm 8, so as tobe adjustable therewith in a direction toward and from the tweezers,although the lens-holder may itself be adjusted in the socket of the arm8 for the purpose of placing said lens-holder in a position whichenables the arm and the lensholder to be folded in an exceedinglycompact relation to the tweezers.

The lens-holder 11 is made from a strip or length of sheet metal whichis curved in crosssection in order to provide an internal seat 12 forthe edge portion of the lens 13, as shown edge on the inside of thelens-holder 11 is adapted to snugly embrace the edge portion of the lensin order to firmly retain said lens in the holder, thus dispensing withlugs, screws, or other devices for confining the lens within themetallic holder. This holder 11 has the end portions of its strip bentoutwardly to form the arms 14, said arms being normally expanded orspread apart, as shown by Fig. 2, owing to the inherent elasticity ofthe divided holder. The arms are adapted to be brought into registeringpositions when the holder is closed upon the lens, and these The curledarms form a shank to the holder, said shank adapted to be thrust intothe socket of the pivoted arm 8. The arms 14 are curved incross-section, also as shown by Fig. 2, and the elasticity of the holdermakes the curved arms frictionally engage with the inner surface of theholder, thus retaining the holder in proper engagement with the socketof the pivoted arm.

In assembling the parts of my implement the lens is first slipped withinthe curled internal edge 12 of the holder, and the arms 14:

, of said holder are then pressed together, so as to close the holderupon the lens. In this condition of the holder the shank formed by saidarms 14 may be thrust into the socket 10, and the lens-holder is thusretained in its closed position by the confinement of its arms withinthe socket. The lens-holder is thus attached to the pivoted arm in amanner to partake of the adjustment of said arm 8 relative to thetweezers. It is evident that the lens and the holder may be turned forthe lens to assume a position wherein one edge of the lens-holderispresented opposite to the space between the members of the tweezers, andthe pivoted arm 8 with the lens attached thereto may now be foldedbetween the members of the tweezers and to the positions shown by Figs.3 and 4, thereby compactly disposing the arm and the lens with relationto and between the leaves or members of the tweezers. In this conditionthe implement can be carried in the pocket oron the person in a veryconvenient manner; but when it is desired to use the implement the arm 8can be swung outwardly on its pivot 9 and the lens-holder can be turnedto a position crosswise of the tweezers, as shown by Fig. 1. Thedistance of the lens from the tweezers may easily be regulated by movingthe arm 8, and the lens is adapted to assume an operative positionacross the free pointed ends of the tweezers. This relative arrangementof the tweezers and the lens enables a mechanic or other person toeasily inspect an object held between the tweezers. For instance, amechanic using the device can hold a machinescrew in the tweezers and byobservation with the lens he can determine whether the threads of thescrew are properly formed on the article. Again, the lens enables aperson to enlarge a part of the hand or fingers into which may beembedded a splinter of wood or other material, and having located thesplinter a person is able to conveniently extract the same bymanipulating the tweezers, the lens and the tweezers being so relatedthat the latter can be easily manipulated while the splinter isunderobservation. Of course the article can be used by other personsthan mechanics and for a variety of useful purposes. The device isextremely simple in construction, efiicient in operation, cheap inmanufacture, and in event of injury to or breakage of the lens it caneasily be replaced by withdrawing the shank of the holder 11 from thesocket 10 of the pivoted arm, after which a new lens can be placed inthe holder and the shank of said holder replaced in the socket.

One extremely useful adaptation of myinvention resides in the fact thatbarbers and others may conveniently extract hairs from the face, the.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Animplementof theclassdescribed,comprisingtweezers formed by a pair of leaves or members, an adjustable armpivoted to said tweezers, and a lens carried by said arm and foldablebetween the leaves or members of said tweezers.

2. An implement of the class described,comprising tweezers formed by apair of leaves or members, acarrying-arm foldable within said leaves ormembers of the tweezers, and alens having an adjustable connection withsaid carrying-arm, said lens being shiftable to a position at rightangles to the tweezers and to a position parallel to the plane of themembers forming said tweezers.

3. An implement of the class described,comprising tweezers formedbyapair of leaves or members, a carrying arm pivoted to said tweezers, alens-holder having a pivotal connection with said arm and foldabletherewith between the members or leaves of said tweezers, and a lens insaid holder.

4. An implement of the class described,comprising apairof tweezers, acarrying-arm pivoted to the tweezers provided with a socket, anexpansible lens-holder having a divided or split shank fitted detachablyand turnably within said socket of the carrying-arm, and a lens held insaid holder.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FREDERICK J. BOEI-IM.
